I have Illustrator CS2 and Photoshop CS2. If I have one of the programs open, then try to open the other, the first program quits. i.e. I can't have both of these programs open at the same time. I have a Mac Pro which is a newer computer than my Apple computer at work and at work, I have no problems with both programs open at once. My operating system is Mac OSX (v 10.4.11). Please, please help!!!! Can e-mail me at: firstname.lastname@example.org
CS2 is not a native intel app. (it was written before Apple was using Intel chips) You have to update to CS3 or above in order to be able to reliably use them simultaneously on an Intel Mac. Sorry!
